  • Patent number: 6223896
    Abstract: An inventive flexible shield and carrying case for laptop computers and other delicate devices are described herein. The flexible shield is preferably made of polyethylene that increases in width from the front of the case to the zipper, and from the back of the case to the zipper. The flexible shield dissipates the force of a blow to the outside of the case and away from the computer. A method is also included for recharging the computer without opening the case, including the steps of providing an adapter, an adapter cord, an adapter port, and a cord retractor, pulling the cord through the adapter port, plugging the cord into a power source, recharging the associated equipment, unplugging the cord from the power source, and retracting the cord.

  • Patent number: 5663322
    Abstract: The present invention is directed to diadenosine tetraphosphate (AP4A) tetrasodium salt dodecahydrate crystals represented by the following structure: ##STR1## Compared with the conventional amorphous anhydride of AP4A tetrasodium salt, the AP4A tetrasodium salt dodecahydrate crystals of the present invention have a low hygroscopicity and very stable physical properties. During storage, they are scarcely affected by environmental humidity. Thus, the present crystals can be easily handled as a medicine or a starting material for preparing a medicine, which broadens their application range.
